| 英文摘要 | A semiconductor laser control apparatus for controlling an optical output of a semiconductor laser to a predetermined value comprises a switching part coupled in series with the semiconductor laser and controlled by an N-bit image signal, N constant current supply circuits coupled in parallel to each other and in series with the switching part for supplying currents to the switching part so that a driving current is supplied to the semiconductor laser from the switching part, a detector for detecting the optical output of the semiconductor laser and for outputting a detection signal indicative of the detected optical output, and a control part responsive to the detection signal from the detector for controlling the driving current by controlling the N constant current supply circuits so that the optical output of the semiconductor laser becomes the predetermined value. |
